Lithosphere Notes on the lithosphere- (rock sphere) Upper most part is crust of earth. Compiled of rocks of outer crust. Outermost shell. Upper part- rocks we see at and near the earths surface. Crust is 5 to 10 km thick under most oceans and 24 to 60 km thick under the continents. The lithosphere under the crust is solid, dense material. (more dense than surface materials). Lithosphere 100-200 km. Notes on the aesthenosphere- zone beneath the lithosphere. Thick like tar. Weak because of high t
Urban Heat Islands
Urban Heat Islands
Urban Heat Islands For more than 100 years, it has been known that two adjacent cities are generally warmer than the surrounding areas. This region of city warmth, known as an urban heat island, can influence the concentration of air pollution. The urban heat island is formed when industrial and urban areas are developed and heat becomes more abundant. In rural areas, a large part of the incoming solar energy is used to evaporate water from vegetation and soil. In cities, where less vegetation a

Our Radiant Planet- Depletion Of The Ozone Layer
Our Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that w

Landfills: A Growing Menace
Landfills: A Growing Menace When asked to think of the largest man made structure, people will invariably come up with an answer like The Great Wall of China, the Great Pyramids, or the Taj Majal. In contrast to these striking achievements of mankind is the Durham Road Landfill outside San Francisco, which occupies over seventy million cubic feet. It is a sad monument to the excesses of modern society [Gore 151]. One must think this huge reservoir of garbage must be the largest thing ever produc

Russia and the Western Republics
Russia and the Western Republics A History of Expansion In the 800s, Vikings settled in a region between the Baltic Sea and Black Sea. In time, they adopted the customs and language of the local Slavic population. In the 1200s, fierce invaders arrived from Mongolia. Mongol warriors controlled the region until the early 1500s. Ivan the Great put an end to Mongol rule. Russia then entered a period of explosive growth. By the end of the 1600s, Russia extended to the Pacific Ocean. The effects of t
